so i just set up my new wireless network. my laptop is the only thing using the wireless part. my desktops are all wired. now i want to know how to secure my network so my neighbors can not use it. it is a linksys router. i do not know much about networking.

You have to go into your internet browser and enter some address, I beleive it is "192.168.2.1" Try and copy that (without the quotations) and paste it into the address bar, no http:// or anything.
If not, Check the linksys manual.

you need to find your default gateway (start>run>type "cmd" then type "ipconfig" in the black box).
type this into your browser.
then login to your router (usually username: admin password: password)
then find the wireless bit and set encryption if it isnt already. id suggest nothing less than wpa. wep is crap and so is having it unsecure
you could have mac filtering aswell but its sooo easy to crack so i wouldnt bother
